Specification of Letters Patent.

Application filed February 14, 1912. Serial No. 677,542.

To all whom it may concern:

Be it known that I, PAUL MERKEL, a subject of the German Emperor, residing at Bohlen, near Rotha, Saxony, in Germany, have invented a certain new and useful Improvementin Processes of Producing Patterns on Hair-Covered Skins, of which'the following is a specification.

The object of this invention is to provide a simple process for producing patterns on hair covered skins.

The invention essentially consists in dyeing the tips of the hairs, then depressing the hairs, on selected portions of a skin, and then shearing off the tips of the und'epressed hairs, so that after the shearing operation and the erect-ion of the hairs which were depressed, the skin exhibits a pattern consistmg of short-haired strips or patches, of the color of the hairs .at their base, and-longhaired strips or patches, of the color of the hairs at their tips.

Apparatus sultable for carrying out this processis illustrated in the accompanying drawing, in which Figure 1 is a side eletation, Fig. 2 a plan we The machine illustrated comprises a plurality of knives a, fixed to a rotatable cylinder 6 and adapted to coact, in shearing, with a knife 0 fixed to a frame adjacent to the cylinder. Rollers (Z mounted as shown in Fig. 1 support an endless conveyer band 6,

by means of which the skin 9 can be "fed past the knife 0 so that the hair on the skin can be clipped by the knives aand c. Nan row bands f of india rubber orv the like pass around the skin on the conveyer band and i hold the skin to the band, and at the 'same time depress the hairs on the strips. which .they cover, so that these -hairs are not clipped by the knives.

By rotating the cylinder a while the skln on the conveyer is traveling past the knives the tips of the upstanding hairs between the bands f are shorn 01f. When the bands f hair-covered skin are subsequently removed from the skin, and the hairs which they have covered are erected, the effect obtained is that of a striped pattern. If the tips of the hairs were dyed, before the shearing operation, the stripes of the pattern are oftwo diflere'nt. colors, namely the color of the dye, where the hairs are not clipped, and the natural color of the hEirs, where the dyed tips have been shorn o By moving the skin to and fro, transversely to the direction of its travel past the knives, during the shearing operation, patterns with undulating or zig-zag stripes can be obtained. The bands f need not be straight edged; their edges may be serrated,"undulating, or otherwise cut so that the bands individually impress regular or irregular patterns in the hair of the skin. Instead of using continuous bands f, pattern sheets of suitable shape and size may be attached to portions of the skin, so as to depress the hair which they cover.

WhatI claim as my invention anddesire to secure by Letters Patent of the United States is 1. The process 01? producing patterns on which consists in dyeing the tips of the hairs, depressing the hairs on selected portions of the skin, and shearing off the dyed tips of the undepressed hairs.

.2. The process of'producing patterns on hair-covered skin which consists in dyeing the tips of the hairs, depressing the hairs on selected portions of the skin by means of covers fastened to the skin, and'shearing off of a shearing machine.

' In witness whereof I have signed this specification in the presence of two witnesses.
